GREASE-CUP LID.

Application filed April 28, 1920.

To all whom it may concern:

Be it known that I, JACOB H. MILLER, a citizen of the United States, residing at Cresson, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Grease-Cup Lids, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to lids for grease cups, and it is an object of the invention to provide a device of this general-character embodying novel and improved means whereby the same may be effectually held in working position and which at all times is maintained against separation from the coacting cup.

It is also an object of the invention to provide a novel and improved lid which has sliding movement either into closed or open position, together with means for imparting the requisite sliding movement thereto, said means also serving to hold the lid at all times against displacement or separation from the cup.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved lid whereby certain important ad vantages are attained and the device ren dered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure l is a view partly in side elevation and partly in section, illustrating a grease cup lid constructed in accordance with an embodiment of my invention and in applied position; and

Fig. 2 is a fragmentary view partly in side elevation and partly in section, illustrating the holding lug carried by the lid and arranged exteriorly of the cup.

As disclosed in the accompanying drawings, C denotes a grease cup of a type particularly employed in connection with the side rods of a locomotive to lubricate a crank pin coacting therewith, although I do not wish to be understood as limiting myself to this particular use.

L denotes a lid for the cup C and which Specification of Letters Patent.

Patented Sept. *7, 1920. Serial No. 377,310.

is of such dimensions and configuration to entirely overlie the upper or outer face of the cup O when the lid is in closed position. The lid L, at a point in close proximity to its periphery is provided. with an inwardly directed lug or wing 1 through which is threaded an operating rod 2.

The operating rod 2 extends radially across the upper or open end portion of the cup C and is provided at one end with a re duced extension 3 having its periphery smooth and unobstructed. The extension is directed through an opening l provided in the side wall of the cup and is of a length in excess of the thickness of said wall so that the outer or extended end portion ofsaid extension 3 may be upset to provide a head 5 whereby the rod 2 is effectively maintained in applied position yet has swivel connection with a wall of the cup C.

The opposite end portion (5 of the rod 2 also has its periphery smooth and unobstructed and said portion 6 extends exterioriy of the cup L) through an opening 7 diametrically opposed to the opening land the extended extremity of the portion 6 or that part thereof exteriorly of the cup C has fixed thereto an operating member 8, prefcrably a knob or wheel of such diameter as to be readily engaged by the digits of a hand. Upon requisite-rotation of the rod 2, through the instrumentality of the head or l-IIlOlJ 8, the lid L will be caused to move either into open or closed position. It is to be particularly noted that the wing or lug 1 of the lid L is at all times in operative engagement with the portion of the rod 2 overlying the outer or open face of the cup 0 so that the lid l) is effectually maintained against complete separation or detachment from the cup C. This is of particular advantage as it often occurs that the type of grease cup lid now generally in use fall off, permitting the grease or lubricant to be shaken out and it also often occurs with the present type of grease cup lids that the lid is forcibly thrown from applied position with liability of disastrous results. lVith my improved lid. these decided disadvantages are effectually overcome and especially when the same is employed with the side rods of a locomotive.

It is also to be particularly noted that with my improved lid, no especial skill or care is required in order to return the lid L into closed position as this operation. is deor recess ll into which the pendent only and entirely upon the requisite rotation of the rod 2. V

lVhile it is not essential to the successful use of my improved lid, I find it of advantage to provide the peripheral portion of the lid at a point remote from the wing or lug 1 with an inwardly directed lug 9, substantially L-shaped in form with the footlO thereof extend 1g inwardly toward the adjacent wall of the cup C. The peripheral face of the cup C is provided with a pocket foot 10 of the lug 9 substantially snugly engages when the lid L has been moved. into substantially complete closed position. By the use of the lug 9, an additional means is provided to hold the lid L against outward movement with respect to the cup C and also tomaterially brace the same in the event an external blow or impact may be imposed thereon and in which event, the lug 9 serves to relieve the wing or lugl from the full force or strain of such blow or impact. I also find it of particular advantage to provide means whereby the lid L is effectually held against vibration when in closed position and for this purpose, I employ a split spring'washer 12, having itsopposed ends laterally off-set in opposite directions to provide the biting teeth 14-. When the lid L is moved into closed position, the teeth 14 frictionally engage the opposed faces of the lug or wing 1 and the wall of the cup C, resulting in the maintenance of the lid L in a firm or fixed position with vibration of the lid L entirely eliminated.

From the foregoing description, it is thought "to beobvious that a lid constructed in accordance with my invention is particularly well adapted for use'by reason of the convenience and facility with which it may be assembledand operated, and it will also be obvious that my invention is susceptible of somechange and modification without departing from the principles and spirit thereof, and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:- 1. In combination with a rease on a lid I V 0 I 9 a 1 for said cup provided with an inwardly disposed lug and a rod rotatably supported by the cun and extendin there-across said rod b L being 111 threaded engagement with the lugs ol the lid, said rod being provided with means for rotating the same.

2. In combination with a grease cup, a lior said cup provided with an inwardly posed lug and a rod rotatably supported the cup and extending thereacross, said 1%); being in threaded engagement with the lug ot the lid, said rod being provided with means for rotating the same, said red e:-; tending radially across the cup.

3. In comb nation with a grease cup, a lid for said cup provided with an inwardly dis:- posed lug and a rod rotatably supported by thecup and extending t lid isiiereacross, said rod being in threaded engagement with the hi5 of the lid, said rod being provided with means for rotating the same, said lug of the lid being positioned adjacent to the periplr ery thereof.

I. In combination with a grease cup, a lid for said cup provided with an inwardly disposed lug and a rod rotatably supported by the cup and extending thereacross, said rod being in threaded engagement with the lug of the lid, said rod being provided with means for rotating the same, and a lor=- p member carried by the rod and coacting with the opposed faces of the lug and the wall of the cup when the lid is in closed position.

5. In combination with a grease cup, a lid for said cup provided with an inwardly disposed lug and a rodrotatably supported the cup and extending thereacross, said being in threaded engagement with the of the lid, said rod being provided wit means for rotating the same, said rod being in swivel connection at one end portion with a wall of the cup and loosely directed through the opposed portion of said wall, the means for rotating the rod being arranged exteriorly of the cup.

In testimony whereof I-hereunto affir; my signature.

JACOB H. MILLER.
